This is more or less a proof of concept, we probably best change the api endpoint data as well to push in/out in the same record so we can also ship the details underneath for those interested.
some people seem to miss the numbers, since the top host graph uses the same information over time, it wouldn't hurt to add a tab containting the raw numbers for the selected interfaces.
The current version doesn't limit the number of results, we might need to add a limit at some point in time, depending on how many results iftop samples.
general remarks:
o total amount of traffic is not being displayed, although we could count the "cumulative" from iftop, the numbers would always be flawed (since sampled with an interval)
o no reverse lookups, maybe for a future version, let's first see if this helps.
o hosts not seen for 120 seconds will automatically be removed from the list (fixed ttl)
